This is a Wedgwood mug. The Conway pattern is from Wedgwood's classic line. This series was manufactured from the 1950s to the 1970s. While plates are occasionally seen, I've hardly ever seen the mugs. It has been carefully stored in a glass cabinet. - Color: Cream - Design: Floral design on the inside - Material: Ceramic - Shape: Ribbed design mug - Size: Medium Thank you for looking.
